Changes (Seu Jorge)

How low can you sing?  The lowest note in the song is an E, and without a microphone amplifying the lower frequencies by being so close, its barely audible.  Its maybe similar to how if you talk into a phone really close to the receiving end your voice will suddenly become very low and bassy even if you're whispering.  If I tried it without a mic, I'd have to capo up maybe 3 steps.  Its fun.
